It breaks fault currents up to 3 kA per both EN 60898 and IEC 60947-2 at 240 V AC, 50 Hz.
Snap-on DIN-rail mount, one width unit (17.5 mm), 55 mm installation depth. Overvoltage category 3 and energy limiting class 3 place it in the standard final-subcircuit position downstream of a main switch or RCD.
3 kA per both EN 60898 and IEC 60947-2 at 240 V AC. That covers standard residential and light commercial fault levels; for higher available fault currents you would need a higher-rated breaker upstream.
